The new principle of pneumatic diaphragm pumps and transport machinery for occasions

Membrane pump is a new type of transportation machinery , is currently one of the most innovative pumps . Using compressed air as a power source for a variety of corrosive

liquid with particles , high viscosity , belt conveyor design volatile, flammable, poisonous liquid can be pumped exhaust . Its pneumatic diaphragm

There are four kinds of material: plastic , aluminum , cast iron, stainless steel. Diaphragm pumps were used NBR, neoprene , Viton , PTFE , depending on the liquid medium , poly

vinyl forty-six . To meet the needs of different users . Placed in a variety of special occasions , normally used for pumping species

Suction pump can not belt conveyor manufacturer regulate the media , have achieved satisfactory results.
A pneumatic diaphragm pump for occasions
Because of pneumatic diaphragm pumps with the above characteristics , so diaphragm in the world since the birth of the pump is gradually into other markets , and some of them

occupied . Such as: painting, ceramics in the diaphragm has an absolute dominance , while in some other industries, such as

Environmental Plastic belt conveyor protection, water treatment, construction , sewage, Fine Chemicals is expanding its market share , and has other pumps irreplaceable . Pneumatic diaphragm

advantages:
1, due to air powered , so flow with backpressure ( outlet resistance ) to automatically adjust to changes , suitable for high viscosity fluids . The centrifugal pump operating

point is water as a benchmark to set a good , if slightly higher viscosity of the fluid, you need to complete reducer or frequency modulation

Speed ​​control , the cost will be greatly improved , the gear pump is the same .
2 , an explosive environment using reliable and low cost pneumatic pumps , such as fuel , gunpowder, explosives transport because: first , it is impossible to produce a spark

after grounding ; Second , the work is no heat generated , the machine does not will overheat ; third , the fluid does not overheat because the diaphragm

Fluid agitation minimum .
3 , at the site of bad places, such as wastewater construction sites, mines , because the sewage impurities and are complicated, easy to plug the pipeline , so that the pump on

form load is too high , the motor heat vulnerability . Pneumatic diaphragm pump can flow through the particle and adjustable tube

Automatically stop when the road to clear blockage .
4 , another small diaphragm easy to move , no foundation , representing the ground is extremely small, easy to install and economical. Materials can be used as portable pump .
5 , there is hazardous , corrosive material handling , the diaphragm material can be completely separated from the outside world .
6 , or the number of tests to ensure that no foreign material contamination .
7, can be used to transport fluids relatively unstable chemical nature , such as : a photosensitive material , such as flocculation liquid . This is because the low- shear

diaphragm little physical impact on the material.
Second, the working principle of pneumatic diaphragm pumps
1 , compressed air powered .
2 , is a deformation caused by the reciprocating diaphragm pump volume change of volume , it works similar to the piston , due to the characteristics of diaphragm pump works ,

so diaphragm pump has the following characteristics : ( 1 ) the pump does not overheat : Compression air as the driving force in the expansion of the exhaust is an endothermic

Process , when the pneumatic pump operating temperature is lowered , no harmful gas emissions. ( 2 ) does not have a spark : pneumatic diaphragm pump without electricity for

power, ground and then prevent static sparks ( 3 ) through a liquid containing particles : Because the volume of imports and ball type work , it is not easy

Blocked . ( 4 ) low shear force on the material : how work is sucked into how vomit , so a minimum of agitation materials for the delivery of unstable substances ( 5 ) flow can

be adjusted , can be installed at the outlet section of the material valve to regulate the flow . ( 6 ) having a self-absorption function. ( 7)

In the dry run , without danger . ( 8 ) can dive work . ( 9 ) can be transported very fluid range from low viscosity to high viscosity , obtained from the viscous resistance . (

10 ) There are no complicated control system, no cables, fuses, etc. . ( 11 ) small size, light weight , they

Mobile . ( 12 ) without lubrication so maintenance is simple and does not pollute the working environment due drip . ( 13 ) pump will always be able to maintain efficient , not

because of wear and tear is reduced. ( 14 ) 100% of energy use , when to close the outlet , the pump automatically shut down, moving equipment , wear and tear, overload, fever

( 15 ) There is no dynamic seal , easy maintenance to avoid leaks. Work no dead spots .
